Further there are arranged support fences 51 to safeguard staff moving on the platform 5, to not fall down. Also, there are cushioning members 83, 84 positioned at the inner edges of the longitudinal platforms 5 that enable the platforms to be positioned in contact with a vehicle B without damaging the vehicle and also closing the space between the platform and the vehicle B so that there exists no gap.
  • Each anchoring mechanism 41 interacts with guide rails 412, 413 (see Fig. 6 ) within each upright 30, such that vertical movement is facilitated at the same time as the anchoring mechanism 41 is fixed in other directions.

  • the difference compared to Fig. 1 is that the two installations 2, 2' shown in Fig.2 may be provided with a crane beam (not shown) that extends across both installations 2, 2'. This may be achieved by not using any longitudinal frame work members 31 at the central part of the joint installations 2, 2', such that a hoist not shown may be moved in between the outer two longitudinal frame work member 31, 31' of the two installations 2, 2'.
